This invention r useful lmprovements magazine for Oll guns,

afford convenient in order to operativ nect the nut to an it will beapparent the nut 10 the latter ly and quickly cessitating any unscrewingor turning of the screw. F When the spring is compressed, it n thebayonet-slots by pressure exerted thereby on the nut. In use, the handleis given as many turns as so desired, which compresses the spring andputs pressure on the oil.

Experience will determine to a nicety the number of turns required inorder to use the gun for oiling a certain number of bear- 85, ingson anautomobile.

After using the gun, thehandle is simply given a turn of two backwardwhich takes all pressure oil all parts, preventing leaking Jf the oilpast the valves or seepage of the oil through the packing. 7 Byproviding a heavy but short spring the capacity of the cylinder ismarkedly increased and the screw serves to place the spring undertension, or to store up powerW 6. degree, which tension is relieved uponturning-of the screw in the reverse direction In Figure 3, a modifiedform of the invention i's illustrated, wherein a flanged nut 0permanently held in its relation to the cylinder, though the screw canbe removed without turning thereof through the nut 20, by removing theholding nut 23.

What is claimedisr- 1. In an oil gun supply magazine, a cylinder havinga piston therein, a spring seated on the piston, a compression followerdisk-(seated on the spring, and an operating screw threadedly connectedto the cylinder and having its lower end depend-i ing within thecylinder; and capable of be mg driven against said disk orfrfeely with-'therefrom to effect or relax the tension on -drawn therefrom, wherebytension on the spring, may be effected or relaxed;

2. In an oil gun supply magazine, a cylinder having a piston therein, aspri-ng seat ed on the piston, a compression follower disk seated. onthe spring, a detachable nut secured to the head of the cylinder, and anoperating screw engaging said nutand having its lower end dependingwithin the cylinder free of said disk and capable of being drivenagainst the latter or withdrawn therefrom to eifect or relax the tensionon disk seated on the rear end of the spring,

an operating screw having its lower end normally positioned within thecylinder and adapted to be in' contact with but unconnected to said diskand capable of being driven toward the latter or withdrawn thespring,-and a nut having a bayonet lock connection with said cylinder,and. mounted on said screw whereby the screw is removable from thecylinder either independent of or in conjunction with said nut, and thebay gnet 'lock is normally maintained by the pressure of the springagainst the follower disk and the operating screw.

In testimony whereof Iaflix my signature hereto.
